Evaluating Airborne Navigation Systems Using Commercial WADGPS Receivers

Steven A. Wright, and Harold A. Klotz Jr.

Abstract:	Significant accuracy enhancements in GPS-aided Inertial Navigation Systems (INSs) and the reliance by applications on this accuracy have driven requirements for more accurate and versatile scoring systems to gauge INS performance during development. These scoring systems are further stressed in airborne applications by aircraft dynamics and the distance the aircraft travels during a test. This paper presents a systematic approach to identify the strengths and limitations of a commercially available global, real-time Wide Area Differential GPS (WADGPS) system for providing high-accuracy, transparent navigation truth in a dynamic airborne environment, without the range limitations inherent in all other scoring means.
